Partial Replacement of Cement with Alccofine to Enhance the Mechanical Properties of Concrete

Abstract: In the construction field, supplementary cementitious materials (SCMs) have brought about a technological revolution in the manufacturing of concrete as a partial replacement or addition to conventional binder mass. Keeping this in mind, this paper aims to summarise and discuss the reported findings on the mechanical and durability properties of alccofine-1203 based concretes. It is also aimed to give a better understanding of the behaviour and effect of alccofine-1203 as an SCM in various types of concretes. The alccofine-1203 has ultra-fine particles with a unique chemical composition that improves the hydration process and pozzolanic reaction. Therefore, its incorporation in concrete has resulted in good workability, reduction in segregation, reduction in heat of hydration, and reduction in permeability to concrete, and increased the rate of hydration process and improved the pozzolanic reaction to achieve high strength to concrete at the early curing stage. The presence of calcium (CaO) and silica (SiO2) in alccofine-1203 improved the mechanical and durability properties of concrete better than the other SCMs. From the literature review, the optimum dosage of alccofine-1203 is obtained between 8% to 12%, and at these percentages, the improvement in mechanical and durability properties of the concrete is highest
